which has the following comment preceding it:

int sock_exec(const char *prog)
It gets called essentially as: sock_exec(getenv("RSYNC_CONNECT_PROG"))
When running the daemon standalone, I see the appropriate behavior. And
with various versions of your command, I'm unable to get any reasonable
output. (Something with permissions on '.', even though I chmod'ed
777
on the temp dir.) And, I see that bind() occurring before I see the
execve() of the RSYNC_CONNECT_PROG (strace -fe trace=bind,process). So,
that bind() is unrelated to the daemon itself (I think).
Best,
